According to the Current Results website, the state of California has a mean annual rainfall of 22 inches, whereas the state of New York has a mean annualrainfall of 54 inches. Assume that the standard deviation for both states is 4 inches. A sample of 30 years of rainfall for California and a sample of 45 years ofrainfall for New York has been taken. Use z-table.a. Show the probability distribution of the sample mean annual rainfall for California.This is a normal probability distribution with E() =22 and oz =4 (to 4 decimals).b. What is the probability that the sample mean is within 1 inch of the population mean for California?(to 4 decimals)c. What is the probability that the sample mean is within 1 inch of the population mean for New York?(to 4 decimals)d. In which case, part (b) or part (c), is the probability of obtaining a sample mean within 1 inch of the population mean greater? Why?The probability of being within 1 inch is greater for New York in part (c) ♥ because the sample size is larger

Given that, The sample size is, n = 45

An engineer is going to redesign an ejection seat for the airplane. The seat was designed for pilots weighing between 150 and 191 pounds. The new population of pilots has normally distributed weights with a mean of 158 pounds and a standard deviation or 31.1 pounds. a. If a pilot is randomly selected, find the probability that his weight is between 150 lb and 191 lb. b. If 38 pilots are randomly selected, find the probability that their mean weight is between 150 lb and 191 lb. what is the approximate probability? c. When redesigning the ejection seat, which probability is more relevant? part b because the seat performance for a single pilot is more important part b because the seat performance for a sample of pilots is more important Part a because the seat performance for a single pilot is more important part a because the seat performance for a sample of pilots is more important. please show solving steps and if possible tell me how to also get these answers through excel…
